I have had exactly the same symptoms as you, I went to the doctors repeatedly and all they could say was that I was depressed or suffering from anxiety, they related all my other physical symptoms to that.
I have made a promise to my self that when I am better I shall help others and train in parasitology, I wish to educate the public and medical profession in the havoc it can cause both physically and psychologically. There are so many people with ill-health that deserve to know the real causes of their illness and not just be sent home with anti-depressents. I am already in to alternative health care and qualified as a Reflexologist 3 years ago which unfortunately I had to give up due to ill-health.
Know what you mean about the doctors thinking your a bit barmy, as soon as you have any kind of psychological symptom you can forget being taken seriously!
The support here is fantastic though and your message has made me feel that i'm not alone with this, thanx
